This edition constitutes a technical revision. This edition includes the following significant technical…
Digital audio interface - Part 4-1: Professional applications - Audio content
IEC 60958-4-1:2016 specifies the format for coding audio used for the audio content. Together with IEC 60958-1, IEC 60958-4-2, and IEC 60958-4-4, it specifies an interface for serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver. This first edition, together with IEC 60958-4-2 and IEC 60958-4-4,…
Digital audio interface - Part 4-2: Professional applications - Metadata and subcode
IEC 60958-4-2:2016 specifies the format for coding metadata, or subcode, that relates to the audio content and is carried with it. This part of IEC 60958, together with IEC 60958-1, IEC 60958-4-1, and IEC 60958-4-4, specifies an interface for serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver. This…
Fertilizers and soil conditioners — Determination of biuret content of urea-based fertilizers — HPLC...
ISO 18643:2016 specifies the test procedure for determination of the biuret content in liquid and solid urea-based fertilizers based on the HPLC method.
Photography and graphic technology — Extended colour encodings for digital image storage, manipulati...
ISO 22028-1:2016 specifies a set of requirements to be met by any extended-gamut colour encoding that is to be used for digital photography and/or graphic technology applications involving digital image storage, manipulation and/or interchange. This part of ISO 22028 is applicable to pictorial digital images that originate from an original scene, as well as digital images with content such as…
Liquid petroleum products — Determination of hydrocarbon types and oxygenates in automotive-motor ga...
ISO 22854:2016 specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline and ethanol (E85) automotive fuel. Additionally, the benzene content, oxygenate compounds and the total oxygen content can be determined.
NOTE 1 For the purposes of this document, the terms % (m/m) and % (V/V) are used to represent…
Acoustics — Description, measurement and assessment of environmental noise — Part 1: Basic quantitie...
ISO 1996-1:2016 defines the basic quantities to be used for the description of noise in community environments and describes basic assessment procedures. It also specifies methods to assess environmental noise and gives guidance on predicting the potential annoyance response of a community to long-term exposure from various types of environmental noises. The sound sources can be separate or in…
Explosive atmospheres — Part 36: Non-electrical equipment for explosive atmospheres — Basic method a...
ISO 80079-36:2016 specifies the basic method and requirements for design, construction, testing and marking of non-electrical Ex equipment, Ex Components, protective systems, devices and assemblies
of these products that have their own potential ignition sources and are intended for use in explosive atmospheres. Hand tools and manually operated equipment without energy storage are excluded from…
Terrestrial photovoltaic (PV) modules - Design qualification and type approval - Part 2: Test proced...
IEC 61215-2:2016 is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well as thin-film modules. The objective of this test sequence is to determine the electrical and thermal characteristics of the module and to show, as far as possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged…
